to improvements in the ard and has particular reference to a method andmachine for making corrugated board in which the corrugations extenddiagonally relative to the edges of the material.

Corrugated fiber board is employed extensively in the manufacture ofboxes or cartons used for shipping purposes and, as is well known, suchboxes are required to meet certain specifications,

particularly with regard to strength. The corrugated board customarilyused at the present time is of the double faced type wherein thecorrugated web, commonly known as the straw",

has its corrugations extending perpendicular to the longitudinal edgesof the sheet from which the box is formed by a creasing or scoringoperation upon the sheet. This known type of board has many advantageswhich have resulted in practically a universal us e of the same for manypurposes but, in some instances, boxes made therefrom have been found tobe lacking in required strength, especially at the corners thereof, andfurthermore the scorings in the board made to form the bottom, sides,etc. of a box have been known to wrinkle said b oard to such an extentas to damage small cartons packed in the box.

It has been heretofore boxes as above referred which the corrugations osuggested to make such to from fiber board in f the straw run diagonallyto the edges of the blank from which the box is formed so that,following the usual scoring and assembly operations, the corrugationswill extend diagonally to the various edges of the box. Such aconstruction results in a box having greater qualities of strength andrigidity, especially at the corners, and eliminates diflicultiespreviously experienced in the scoring operation owing to the fact thatall creasing of the board is done in directions transverse to thecorrugations.

HOW-

ever, attempts heretofore made to design a commercially practicalmachine for manufacturing diagonally corrugated boxes have not met withsuccess. plish the desired end hav use of a corrugating roll Previousexperiments made to accome generally included the of the spiral type.Such a roll not only necessitates the designing of practically an entirenew machine from the kind now in use, but it has been found that theroll frequently breaks the material, thereby lmaking the ultimate costof production too high for commercial purposes.

ture diagonally corrugate d board, the present invention has beendesigned, and in accomplishing the desired result it has been madepossible to utilize standard types of corrugating, gluing and othernecessary machines without material alteration therein.-

In accordance with one of the features of the invention, it is proposedto divide into a plurality of sections a continuous length of corrugatedmaterial in which the corrugations extend perpendicularly to edges ofsaid length, and then assemble said sections into another continuouslength wherein the corrugations run diagonally relative to said edges.

Another feature is to apply a liner to a continuous web of material inlaterally offset relation thereto and then cut said web and liner ondiagonal lines to form a plurality of sections which are subsequentlyassembled into another continuous length in which the corrugationsextend diagonally and a portion of the liner of each section overlaps apart of the corrugated web of a next adjacent section.

A further feature is to feed a continuous length of corrugated materialto a cutter at a certain speed to divide said length into a plurality ofsections which are subsequently made to move at a greater speedduring-which they are turned so that their'cut edges extend in thedirection of the longitudinal movement thereof, after which the speed ofthe sections is retarded to enable them to come into abutting relationand then be assembled into another continuous length.

- The above and other objects will appear more clearly from thefollowing detailed description, when taken in connection with theaccompanying drawings, which illustrate a preferred embodiment of theinventive idea.

As hereinbefore indicated, the novel mechanism embodying thecharacteristic features of the present invention and generally indicatedby the character A in Figure l is capable of being used in conjunctionwith a standard type of corrugating machine B and gluing andliner-applying mechanism C, said mechanism A being interposed betweenthe apparatus B and C which, in the manufacture of the ordinary doublefaced fiber board, are directly joined to each other. A briefdescription of the corrugator B will be sumcient for a completeunderstanding of the mode of operation of the present machine. Thefunction of the corrugatonB is to produce a continuous length of singlefaced corrugated material and this is accomplished by feeding a web ofstraw 10 and a facing liner 1l through a corrugating and gluingapparatus, generally indicated by the numeral 12, where the straw iscorrugated and attached to the liner, thereafter being led from themachine-over the guide rollers 13 and 14. In the manufacture of ordinary4corrugated fiber board, the corrugations are made perpendicular to thelongitudinal edges of the straw web 10 and the liner 11, which is of thesame width as the web, is applied thereto with their longitudinal edgesin registration. However, in accordance with the present invention, itis proposed to apply the liner to the web in laterally offset relationso that a portion 15 (Figure 4) of one longitudinal edge of the linerwill project slightly beyond the adjacent edge of the web. while theopposite edge of the liner will terminate short of the contiguous edgeof the' web, thus leaving a portion 16 of the latter exposed. During thepassage of the web and liner through the corrugator the adhesive isapplied across the entire width 10 after it has been corrugated in thesame manner as usual so that the small exposed portion of the web whichprojects from one edge of the liner will also have adhesive thereonwhich later is employed in the assembly of the sections which are cutfrom the continuous length of material as it is fed from thecorrugato'r. The offset relationship between the web 10 and liner 11 maybe obtained by simply shifting laterally the roll from which the liner11 is drawn. The single faced corrugated board is now withdrawn from thecorrugator B by passing the same between a pair of feedrolls 17 drivenfrom the corrugating machine by a drive belt 18 which causes the boardto be fed to thevmechanism A at a certain predetermined speed. Thecontinuous strip of material is now ready to be cut into sections eachof which successively has its position shifted relative to that in whichit was located immediately subsequent to its severance from thecontinuous strip of board, and

then assembled into another continuous length of material with thecorrugations running diagonally across the board.

As previously explained, the corrugations in the straw run perpendicularto the longitudinal edges of the web 10, but in accomplishing theresults of the -present invention it is immaterial whether suchl-corrugations extend in the above manner, or run longitudinally of theweb. As' the single faced board is fed between the rolls 17\ itapproaches a cutting mechanism which is intermittently operated to severfrom the board a section of predetermined length, which length forms thewidth of the board after the sections have been assembled to constitutethe second continuous strip of material which is the iinal product ofthe machine. Said cutting mechanism comprises upper and lower cuttingrollers 19 and 20 arranged diagonally across the machine andconsequently in a diagonal direction relative to the corrugations in theweb 10, and adapted to have the board fed between the same by the rolls17. The cutting roller 19 has a knife -edge 21, while the roller 20 hasa groove 22 therein for receiving said edge as the rollers operate tosever the material. The rollers 19 and 20 are rotated intermittentlyunder the control of the sheet of material as it passes between the sameand when so rotated they make one complete revolution. This operation isaccomplished in thefollowing manner: As the forward end of the materialpasses under a weighted roller 23 (Figure 4) which holds the sheet down,the front edge of the latter strikes the upper end of a rocker arm 24normally supported in a vertical position upon an oscillatory shaft 25,the ends of which are mounted in bearings 26 which are adjustablycarried upon rods 27 arranged beneath the frame of the machine. Theengagement of the material with said rocker arm causes the upper end ofthe latter to swing to the left, as viewed in Figure 5, with the resultthat the link 28 adjustably secured to the lower end of said arm ismoved to the right to operate a lever 29 pivoted at 30. The movement ofthis lever is employed to control a clutch mechanism to couple the uppercutting roller 19 with the drive for the cutting mechanism. This drivecomprises two spiral gears 3l and 32 (Figure 4) continuously driven fromthe shaft 33 extending transversely of the machine which is rotated in amanner to appear in the course of the description. The shaft 34 uponwhich the continuously rotating gear 31 is mounted also drives theclutch member 35 having a recess 36 therein. Associated with the member35 is a second clutch member 37 in which is slidably mounted aspring-pressed plunger 38 adapted to engage in the recess 36 when theclutch members 35 and 37 are connected so as to cause rotation of thelatter member which is carried by the roller 19. Normally the plunger 38is held in a retracted position from the recess 36 by means of a pivotedlatch 39 extending into a slot 40 in the outer end of the plunger 38.The free extremity of the, latch 39 is normally engaged by a trip 41carried by the lever 29. Thus, as said lever is rocked as previouslydescribed, the trip 41 will elevate the latch 39 and disengage the samefrom the slot 40 in the plunger 38, thus permitting the spring of thelatter to force it into the recess 36. Just prior to this action takingplace the knife 21 and groove 22 are in the position shown in Figure 5,from which position only a slight movement of the rollers is necessary pto bring said elements into cooperative relation 4lll) to,sever theboard along a line which is diagonal to the corrugations in the web 10,whether these corrugations run transversely or longitudinally of saidweb. Asthe latch 39 reaches the extremity of its upward movement underthe lifting inlluence of the trip 41, the latter passes beyond the endof said latch permitting the same to return to its normal position. Atthis time the plunger 38 has been carried away from the latch by therotation of the clutch members 35 and 37 and'the knife 21 and slot 22have cooperated to sever a section from the length of board. Also, thesection is being conveyed, in a manner to presently appear, away fromthe cutting mechanism and is passing over the rocker arm 24. When theedge of the section which has just been cut has passed beyond and out ofengagement with the rocker arm 24 a spring 42 acts to restore the lever29 and said rocker arm to normal position. In doing so the latch 41which is pivoted to the lever 29 rides over the extremity of the latch39 and again assumes the position shown in Figure 5. In the meanwhile,the rollers 19 'and continue to be driven until a complete rotation hasbeen made. As said rollers near the end of their rotation the plunger 38aproaches the latch 39 and the latter enters the slot 40. Said latch isprovided with a cam 43 which, as the latter action occurs, engages anedge of the slot 40, as seen in Figure 6, and continued movement of theplunger causes the latter to beI withdrawn by said cam from the recess36. Upon complete withdrawal, the clutch member 37 continues to rotate,but the member and the rollers 19 and 20 come to a stop, the latterhaving been driven through its rotation by the gears 44 and 45 carried,respectively, by the ends of the rollers 19 and 20 remote from theclutch mechanism.

Returning now to the point in the operation where the forward end of theuncut board is being passed between the cutting rolls and prior to saidend engaging the rocker arm 24, means are provided intermediate saidcutting mechanism and rocker arm and at one side of the machine forengaging the flange formed by the projecting edge 15 of the liner 11 toturn said ange upwardly, as indicated in Figure 9, for a purpose whichwill appear in the course of the description. This means comprises apair of superposed rollers 44a and 441) carried in an inclined positionby a guide 45a extending longitudinally of the machine. As said ange 15engages between the rollers 44a and 44h it is turned up slightly andremains in this position until the variously cut sections are assembledin the final product.

The length of the severed section, which ultimately becomes the width ofthe nished product, may be varied at will by adjusting the rocker arm 24toward and away from the cutting rolls. This is done by' loosening thebearings 26 and the connection of the lower end of the arm 24 with thelink 28 and then moving said bearings with said arm and the shaft 25longitudinally along the rods` 27 until the desired position is reached,whereupon the bearings 26 are secured in their adjusted positions andthe link 28 is fixed to said rocker arm.

The severed section is now conveyed away from the cutting mechanism at aspeed greaterl than that which is imparted by the rollers 17 to thecontinuous length of material. This conveying is accomplished throughthe intermediary of a plurality of longitudinally extending conveyorbelts 46 which extend around pulleys carried by the shafts 47 and 48arranged transversely of the machine at opposite ends of the mechanismA. Said conveyor belts also are engaged with a series of intermediateidler pulleys 49 (Figure 8) revoluble upon the stationary shaft -50supported in the sides of the machine, these intermediate pulleys beingprovided to prevent sagging of the belts. The drive for the shafts 47and 48 is effected from the mechanism-C which derives its power from asuitable source (not shown) through the drive element 51 (Figure 3a)This power is then transmitted through the chain 52 or other endlesselement to the shaft 48 and thereby to the various conveyor belts 46.The rotation of the shaft 48 is such as to drive the belts at anincreased speed over that of the travel of the board before it is cut soas to carry each cut section away from the adjacent end of the followingsection about to be cut to permit said cut section to be turned ln amanner to presently appear and as indicated by the dot and dash lines inFigure 4.

Shortly after the forward end of the cut section has passed on to theconveyor belts 46 the forward diagonal edge of said section engages witha means for effecting a shift in the position of the section from thatwhich it assumes as it passes on to the conveyor belts from the cuttingmechanism to the position wherein the diagonally cut edges of thesection are extended in' the direction of movement of the sectionsthrough the machine. This shifting movement which is in the plane of thesection then brings the latter to the position where the corrugations inthe web 10 extend diagonally relative to the then longitudinal edges ofthe section, as shown toward the right of Figure 4. The means foraccomplishing the turning or shifting of each section comprises anendless belt 53 arranged towards one side of the machine so as to engagea section adjacent the projecting portion 16 of the web 10, said beltextending around two pulleys 54 and 55 and over a large idler pulley 56which causes a portion of the belt to be elevated above the belts 46.The pulleys 54 and 55 are carried, respectively, on shafts 57 and 58,the latter of which is driven off of the shaft 48 by means of the chain59. The sprocket carried by the shaft 58 and with which the chain 59engages is smaller than the sprocket on the shaft 48 so that the shaft58, and consequently the belt 53, will be driven at an increased speedover that of the belts 46. By reason of this increased speed and thefrictional engagement oi the belt 53 with the under side of the sectionthe latter has imparted thereto a turning movement at the same time thatit is being moved forwardly. Immediately following the engagement of theforward edge of the section with the belt 53, said section will comeinto contact and ride over a guide 60 which is coextensivelongitudinally with the belt 53 and which is also inclined downwardlytransverse of the machine, as best shown in Figure 8. To facilitate themovement of the section over the guide 60, the then elevated portion ofsaid section is engaged by a soft felt roll 61 which may be driven fromthe shaft 58 by a chain 62. To prevent any possibility of the sectionsliding oif of the guide 60 in the direction of the side of the machine,the conveyor belt 46 at the extreme left of Figure 8 is provided with araised portion 63 against which the lower edge of the section abuts asit is being moved along. As the section is being turned it rides overthe guide 60 and then4 again passes on to the conveyor belts 46 at whichtime it is in its completely turned position, as shown at the right ofFigure 4.

ward the mechanism C in slightly spaced relation to the precedingsection. As each section approaches the mechanism C it engages a guide64 which is adjustable to the width of the finished product, that is thelength of each section before the latter is turned, and then passesbetween the superposed pressure rolls 65 which are driven by the shaft48 through the medium of a chain 66 at a slower'speed than that of saidshaft. This slower speed of the pressure rollers retards the saidfollowing section passes under the flange 15\" of the section in frontthereof, which flange at this time is slightly raised, as indicatedatthe left of Figure 2, this raising of the flange having beenaccomplished by the rollers 44a and 44h. After' this has beenaccomplished the overlapping portions of the adjacent sections passbetween the pressure rolls 65 which then force the flange 15 downwardlyinto contact with the portion 16 having the adhesive thereon. Theadjacent sections are thus assembled and securely connected to eachother, whereupon they pass to the gluing or adhesive-applying apparatusof the mechanism C preparatory to having a backing liner applied to theunder surface of the web 10. Briefly, the gluing apparatus (Figure 3a)comprises a large roll 67 partially immersed in a reservoir loi adhesiveand driven in the direction of the arrow by the endless element 68.Contacting with the roll 67 is a Small adhesive-applying roll 69 whichengages with the under surface of the web 10 to apply adhesive thereto,there being a weighted roll 69a superposed above said roll 69 to engagethe upper surface of the material. As soon as the continuous length ofmaterial passes from the gluing apparatus, the backing liner 70, whichis fed from a roll 71 and which extends around a roller 72, is broughtinto contact with the under surface of the web 10 and adheres thereto.From the mechanism C the finished product passes on to the customarydrying apparatus (not shown) and after coming therefrom is ready to becut into suitable lengths.
